Bridge Scour Analysis in New Jersey: Which Scour Factors Matter Most?
This paper seeks to correlate the scour susceptibility of bridges with such observable characteristics as bridge design features, waterway characteristics, and geographic and geologic...
Economics of Floods, Scour, and Bridge Failures
Hydraulic events occur more often and account for more losses than any other natural disaster. The damage inflicted on our nation's highway facilities during these events not only results...
Pier Scour Equations Used in China
This report describes the equations used in the People's Republic of China for estimating scour depth at bridge structures. The equations were worked out from model and field data at the...
Scour at Highway Structures in Tidal Waters
Scour analysis of bridges over tidal waterways uses the same scour equations as for the rivers. However, determining the hydraulic variables to use in the equations is complex. A major...
Emergent Techniques in Scour Monitoring Devices
This paper presents a brief status report of a research and development project funded by the National Cooperative Highway Research Program (NCHRP) to develop and test scour monitoring...
Practical Comparison of One-Dimensional and Two-Dimensional Hydraulic Analyses for Bridge Scour
The Kentucky Transportation Cabinet, Department of Highways is working with the Indiana Department of Transportation and the Federal Highway Administration to plan, design, and construct...
The Design and Development of A Road/Rail Power Unit
The road/rail power unit was designed and developed by Saskatchewan Highways and Transportation to provide low cost motive power on low-density disconnected rail lines. The power unit...
Washington State Pavement Management System

PMS Implementation: Guidelines and Lessons Learned
Pavement management has emerged throughout the 1980s as an accepted tool to assist engineers in planning their pavement rehabilitation needs. Boosted by the support of the Federal Government...
Application of Leading Edge PMS Techniques in India
In India there is a pressing need for an efficient system to plan highway rehabilitation and maintenance. A two year project has started in March 1993 to develop a Pavement Management...
Canadian Pavement Management Systems
A large portion of the investment in Canada's road system is in pavement structures. In the 1960's a coordinated national effort toward protecting the investment, through good pavement...
Compare: Hampton Roads Congestion Management Program
COMPARE is an acronym given to a traffic congestion management program that has been formulated through the cooperative efforts of all the major Cities and Transportation Agencies in the...
Trip Rates Adjustments for Impact Assessment and Congestion Management
Evidence that all urban trips are not equal and that trip rates need to be adjusted to reflect the differential contribution of trips to traffic loads and congestion is presented. Adjustments...
Field Testing of Advanced Maintenance Data Acquisition Technologies in Three State DOTs
Field testing and evaluation of advanced data acquisition technology in Maryland, Connecticut and Arizona showed the potential for state highway agencies to improve existing procedures...
BMS Modelling of Bridge Stock Performance
A computer-based Bridge Management System, BMS, was designed in Finland by the Finnish National Road Administration (FinnRA) to assist in high level bridge policy, long-term planning and...
Level of Service in Bridge Management Systems
The Federal Highway Administration's Sufficiency Rating is not adequate for evaluating bridges. It ignores fundamental bridge characteristics and is far too subjective. The Level of Service...
Congestion Pricing with Tolls and Subsidies
Though economists have promoted congestion pricing for many years it has, in general, met with public opposition. It is usually argued that congestion pricing is unfair, discriminatory,...
